  • Patent number: 6223092
    Abstract: A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized with work easy to do in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. A server machine section of the system includes an evaluation-destined element estimating module for estimating the evaluation-destined elements to be performed on parts constituting an article given by a design plan subjected to evaluation, a part workability evaluation module for evaluating easiness of works to be performed on the parts, an article workability evaluation module for evaluating easiness of works involved in realizing the article, and a best design plan selection/determination module for selectively determining a best structure on the basis of comparative evaluation of a plurality of design plans.

  • Patent number: 6122560
    Abstract: A method or device for computing material requirements which calculates various parts and materials necessary for products to be produced when a production plan is input, in order to reduce the processing time for a material requirements computation. In order to establish the object, the method or device of computing material requirements is provided, which can perform a parallel process without using conventional low level codes. Parts computing means are respectively assigned to items. When the lower parts computing means receives the computation result of the upper parts computing means, it independently executes the computing process if the computation result is sufficient for the parts computation.

  • Patent number: 5717598
    Abstract: A designed object workability evaluating system for evaluating quantitatively at a stage of designing an article whether a structure of the article as designed can be realized easily in a manufacturing stage for thereby selectively determining a best structure from a plurality of design plans through comparative evaluation thereof. The system includes a client machine section including a guide information generating unit for generating information for guiding operations of a user, an input device for allowing the user to input commands and data and a display unit. A server machine section includes a registering unit storing evaluation elements defined by the user, an index calculating module for calculating indexes indicating degrees of difficulty/ease of work, an evaluation element estimating module, a part workability evaluation module, an article workability evaluation module, and a best design plan selection/determination module.
